Description

Technical Field

[0001] The present invention relates to a manure cleaning and disinfecting device, in particular to an automatic manure cleaning and disinfecting integrated device, belonging to the technical field of breeding equipment. Background Art

[0002] In the modern large-scale laying hen farming process, a corrosion-resistant PP conveyor belt is installed under each layer of chicken cages to transport manure to the end of the chicken house on a regular basis every day, and a scraper is used to ensure that "manure does not fall to the ground". However, during the manure cleaning process, manure is easily accumulated on the scraper, affecting the feeding and cleaning effect of chicken manure. It is difficult to clean the surface of the conveyor belt only by scraper cleaning. The unclean conveyor belt will rotate to the top of the chicken cage below and cause bacteria to grow. In addition, it is impossible to automatically disinfect after manure cleaning. If spray disinfection is used, the droplets will be suspended in the air. After inhalation by the chickens, it may irritate the respiratory mucosa, causing coughing, respiratory inflammation, etc.

[0003] Therefore, an automatic feces cleaning and disinfection integrated device is designed to optimize the above problems. Summary of the Invention

[0004] The main purpose of the present invention is to provide an integrated device for automatic feces cleaning and disinfection, which has a V-shaped scraper fixed between the end plates at both ends and in contact with the conveyor belt, and the top of the V-shaped scraper is in contact with the conveyor belt, so that feces can be scraped off during the movement of the conveyor belt, and then high-pressure water is sprayed out through the nozzle inside the V-shaped scraper for flushing, thereby performing double cleaning, thereby improving the cleaning effect during use, and at the same time, during the feces scraping process, a loosening mechanism composed of a guide groove, a cross bar, a shifting rod, a sliding sleeve, a positioning column, a shaft rod, a dial wheel, and a vertical rod can be used to drive the shifting rod to move back and forth on the surface of the V-shaped scraper, effectively avoiding the accumulation of feces. In addition, the nozzle is connected to the cross bar by the vertical rod, and the reciprocating movement of the nozzle can be simultaneously driven during the high-pressure flushing process, thereby improving the flushing effect. A disinfection filter box is provided at the bottom of the V-shaped scraper, and a filter screen is provided inside the disinfection filter box, so that the liquid can be collected and recycled, and then a circulation mechanism composed of a first sleeve, a one-way liquid inlet valve, a conduit, a one-way liquid discharge valve, a first piston, a connecting rod, and a fixed rod can be used to clean feces. During the process, a linkage method is adopted to automatically extract the liquid inside the disinfection filter box for cyclic flushing. In addition, by adding disinfectant inside the disinfection filter box, disinfection can be carried out simultaneously during the flushing process, thereby improving the functionality of the device. After disinfection, the strip scraper is used to remove excess water stains on the surface of the conveyor belt, so that the disinfectant liquid disinfects the surface of the conveyor belt by smearing, effectively avoiding the impact of droplet suspension on the health of the chicken, thereby improving the safety of disinfection. A dredging mechanism consisting of a second sleeve, a through pipe, a second piston, a first spring, a connecting rod, a slide plate, a discharge pipe, a chute, an insert, a second spring, and an annular groove is provided between the disinfection filter box and the collection tank. The second sleeve is connected to the disinfection filter box. When the top of the filter is clogged, the inside of the disinfection filter box is in a negative pressure state, and the pressure is greater than the resistance applied to the second piston by the insert. The second piston will automatically control the movement of the slide plate to scrape the feces on the top of the filter into the inside of the discharge pipe, and the top of the filter will be automatically cleaned, thereby improving the functionality of the device.

[0036] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0037] like Figures 1-8 As shown, this embodiment provides an automatic feces cleaning and disinfection integrated device, including a frame 1, end plates 101 symmetrically arranged on both sides of the end of the frame 1, conveyor rollers 102 rotatably mounted between the two sets of end plates 101, a conveyor belt 103 between the outer sides of the two sets of conveyor rollers 102, made of corrosion-resistant PP material with a thickness of 3-5 mm and a surface roughness of Ra ≤ 1.6 μm to reduce feces adhesion, a drive motor 104 installed on the top of the end plate 101, and a pulley assembly 105 between the drive motor 104 and the conveyor rollers 102;

[0038] A V-shaped scraper 2 is provided between the inner sides of the two sets of end plates 101 and parallel to the length direction of the conveyor roller 102. The edge of the V-shaped scraper 2 is plated with hard chrome (thickness 5-10 μm) with a hardness ≥ HV800 to improve wear resistance. The top end of the V-shaped scraper 2 is attached to the surface of the conveyor belt 103.

[0039] The V-shaped scraper 2 is fixed to the inner side of the end plate 101 by a bolt group. The bolt group is equipped with a spring washer (elastic coefficient 15-20N / mm) to ensure that the top of the V-shaped scraper 2 and the conveyor belt 103 maintain an elastic fit of 0.5-1mm, allowing the V-shaped scraper 2 to slightly jump with the conveyor belt 103 without damaging the surface. A gap is left between the bottom end of the V-shaped scraper 2 and the surface of the conveyor belt 103;

[0040] A collecting trough 4 is provided at the bottom between the two sets of end plates 101, and a loosening mechanism 3 is provided at the top of the V-shaped scraper 2;

[0041] A nozzle 5 is provided inside the V-shaped scraper 2 along the length direction, and a spray hole is evenly opened on the side of the nozzle 5 close to the conveyor belt 103. The diameter of the spray hole is set to 0.8-1.2 mm, and the outlet pressure is controlled at 0.3-0.5 MPa to prevent high-pressure water from splashing or damaging the conveyor belt 103. A disinfection filter box 6 is provided vertically below the V-shaped scraper 2. The top of the disinfection filter box 6 is provided with a strip scraper 7 along the length direction that is in contact with the bottom of the conveyor belt 103;

[0042] The strip scraper 7 is made of polyurethane elastomer (hardness Shore A80-90) and is installed on the top of the disinfection filter box 6 through an adjustable bracket. The bracket is provided with an oblong hole, and the fitting pressure between the strip scraper 7 and the bottom of the conveyor belt 103 can be controlled by adjusting the bolt (0.2-0.3N / mm 2 ), ensuring that water stains are scraped off without scratching the conveyor belt 103;

[0043] The top of the disinfection filter box 6 is provided with a drainage bucket 8, and the bottom of the drainage bucket 8 is horizontally installed with a filter screen 9, which is made of 304 stainless steel woven mesh with a mesh number of 80-100 and a pore size of 0.15-0.2mm, taking into account both filtering effect and flow capacity;

[0044] A vacuum pump 10 is provided below the frame 1, the input end of which is connected to the interior of the sterilizing filter box 6;

[0045] The vacuum pump 10 uses a diaphragm pump with a power of 100-200W and a pumping rate of 5-10L / min to ensure that the negative pressure in the disinfection filter box 6 is stable at 10-20kPa to accelerate liquid filtration;

[0046] A circulation mechanism 11 is provided between the end of the disinfection filter box 6 and the nozzle 5 , and a dredging mechanism 12 for cleaning the top of the filter screen 9 is provided between the disinfection filter box 6 and the collecting tank 4 .

[0047] The overall working principle is as follows: the conveyor belt 103 is located below the chicken cage, and the chicken manure falls on the top of the conveyor belt 103. When the chicken manure is cleaned, the drive motor 104 is started to control the chicken manure on the top of the conveyor belt 103 to move toward the direction of the V-shaped scraper 2. The V-shaped scraper 2 scrapes the chicken manure, and then the chicken manure falls into the inside of the collecting trough 4. Due to the different dryness and wetness of the chicken manure, it will adhere to the top of the V-shaped scraper 2. Therefore, during the manure cleaning process, the loosening mechanism 3 is used to move back and forth on the top of the V-shaped scraper 2 to prevent the chicken manure from adhering. After the preliminary cleaning, the circulation mechanism 11 is used to extract the liquid inside the disinfection filter box 6. The liquid in the disinfection filter box 6 contains disinfectant. When replenishing the fluid, sodium hypochlorite with a concentration of 0.1%-0.3% is injected from the top of the disinfection filter box 6. The circulation mechanism 11 is used to extract the liquid inside the disinfection filter box 6. The liquid in the disinfection filter box 6 contains disinfectant. When replenishing the fluid, sodium hypochlorite with a concentration of 0.1%-0.3% is injected from the top of the disinfection filter box 6. The mechanism 11 discharges the liquid from the nozzle on the nozzle 5, rinses the surface of the conveyor belt 103, and performs a sterilization operation. The dripping water stains fall into the interior of the disinfection filter box 6 again and are filtered by the filter screen 9 for recycling. After rinsing and disinfection, the strip scraper 7 is used to scrape off the excess water stains at the bottom of the conveyor belt 103 to ensure that the disinfectant is disinfected in a smearing manner, which is safer. When the dripping water stains enter the disinfection filter box 6 for filtration, the vacuum pump 10 is started to generate negative pressure inside the disinfection filter box 6 to speed up the filtration. The feces will be intercepted at the top of the filter screen 9. When there is too much feces on the filter screen 9 and it causes blockage, the dredging mechanism 12 is used to dredge the surface of the filter screen 9 and guide the feces into the interior of the collection tank 4.

[0048] In this embodiment, the loosening mechanism 3 includes a guide groove 301, a cross bar 302, a shift rod 303 and a reciprocating assembly. A guide groove 301 is provided at the top of the V-shaped scraper 2 along the length direction, and a cross bar 302 is slidingly provided inside the guide groove 301 along the length direction. The top of the cross bar 302 is evenly provided with a shift rod 303. The shift rod 303 is perpendicular to the guide groove 301 and fits on the top of the V-shaped scraper 2. A reciprocating assembly is provided at the end of the cross bar 302.

[0049] Partial working principle: During the manure cleaning process, the reciprocating assembly will drive the cross bar 302 to slide back and forth inside the guide groove 301. The top of the cross bar 302 is located at the same horizontal plane as the V-shaped scraper 2 and will not be blocked by chicken manure. During the movement, the cross bar 302 will drive the lever 303 to slide back and forth on the surface of the V-shaped scraper 2 along the length direction, stirring the chicken manure to prevent it from sticking.

[0050] In this embodiment, the reciprocating assembly includes a sleeve 304, a positioning column 305, a shaft 306 and a thumbwheel 307. The sleeve 304 is fixed to the outside of the end plate 101. The cross bar 302 passes through the end plate 101 and passes through the inside of the sleeve 304. The cross-sectional shapes of the ends of the sleeve 304 and the cross bar 302 are both rectangular. The ends of the cross bar 302 are symmetrically provided with positioning columns 305. The ends of the conveying rollers 102 are all fixed with shafts 306, and thumbwheels are all fixed on the shafts 306. 307, the dial 307 is located between the two groups of positioning posts 305, and the outer peripheral surface of the dial 307 is set as a symmetrical arc-shaped push surface. The inclination angle of the push surface when contacting the positioning post 305 is 30°-45°, ensuring that a horizontal thrust is applied to the positioning post 305. The spacing between the two groups of positioning posts 305 is 1.2-1.5 times the diameter of the dial 307, ensuring that the positioning posts 305 on both sides are alternately stressed when the dial 307 rotates, driving the cross bar 302 to perform a linear reciprocating motion in the sliding sleeve 304.

[0051] Partial working principle: During the chicken manure cleaning process, the rotation of the conveyor roller 102 will drive the rotation of the shaft 306, and the shaft 306 will drive the dial 307 to rotate. Since the dial 307 is tilted on the shaft 306 and the dial 307 is located between the two sets of positioning columns 305, during the rotation of the dial 307, the raised portion of the dial 307 first pushes the positioning column 305 on one side, causing the cross bar 302 to slide to one side. After the dial 307 rotates 180°, the raised portion on the other side pushes the positioning column 305 on the opposite side, and the cross bar 302 slides in the opposite direction, realizing periodic reciprocating motion, and the frequency matches the rotation speed of the conveyor roller 102.

[0052] In this embodiment, an L-shaped plate is fixed to the outer side of each end plate 101 , and the end of the shaft 306 is rotatably mounted on the L-shaped plate.

[0053] Partial working principle: The setting of the L-shaped plate limits the position of the shaft 306.

[0054] In this embodiment, vertical rods 308 are vertically fixed below the ends of the horizontal rods 302 , and the two ends of the nozzle 5 are respectively fixed on the two sets of vertical rods 308 .

[0055] Partial working principle: During the reciprocating movement of the horizontal rod 302, the use of the vertical rod 308 will drive the nozzle 5 to move back and forth, performing active flushing to improve the flushing effect.

[0056] In this embodiment, the circulation mechanism 11 includes a first sleeve 1101, a one-way liquid inlet valve 1102, a conduit 1103, a one-way liquid discharge valve 1104, a first piston 1105, a connecting rod 1106 and a fixed rod 1107. The first sleeve 1101 is fixed at both ends of the disinfection filter box 6. A one-way liquid inlet valve 1102 is provided between the two groups of first sleeves 1101 and the ends of the disinfection filter box 6. A spherical check valve is adopted, and the valve ball diameter is 8-10mm. The valve seat is opened at the connecting port between the disinfection filter box 6 and the first sleeve 1101, and the opening pressure is ≤5kPa, which ensures that the liquid flows from the disinfection filter box 6 into the first sleeve 1101. The first A conduit 1103 is provided between the end of the sleeve 1101 and the nozzle 5, and a one-way liquid discharge valve 1104 is provided on the conduit 1103. A diaphragm check valve is adopted, and the diaphragm material is nitrile rubber. It is opened at the connection between the conduit 1103 and the nozzle 5, and the opening pressure is ≥10kPa to prevent the high-pressure liquid in the nozzle 5 from flowing back. A first piston 1105 is slidably provided inside the first sleeve 1101, and a connecting rod 1106 is fixed to the outside of the first piston 1105. The first piston 1105 and the connecting rod 1106 are hinged by a pin, and a fixing rod 1107 is fixed between the ends of the two sets of connecting rods 1106 and the end of the cross bar 302.

[0057] Local working principle: During the reciprocating movement of the cross bar 302, the first pistons 1105 inside the two groups of first sleeves 1101 will be controlled to slide at the same time. The interior of one group of first sleeves 1101 is in a water intake state, and the interior of the other group of first sleeves 1101 is in a water discharge state, realizing alternating suction and discharge, and continuously injecting water into the nozzle 5 to ensure continuous flushing. The linkage control method is adopted, which is more energy-saving and more convenient to control. The stroke of the first piston 1105 in the first sleeve 1101 is consistent with the stroke of the cross bar 302.

[0058] In this embodiment, the dredging mechanism 12 includes a slide 1206, a discharge pipe 1207 and a pulling assembly. The slide 1206 is parallel to the length direction of the disinfection filter box 6 and is attached to the top of the filter screen 9. The slide 1206 is located on the side of the top of the filter screen 9 away from the collection tank 4. A discharge pipe 1207 is provided between the side of the disinfection filter box 6 and the collection tank 4. A sliding rod is horizontally fixed to the bottom end of the drainage bucket 8 along the width direction. The slide 1206 is slidably connected to the sliding rod, and a pulling assembly for controlling the horizontal sliding of the slide 1206 is provided on the top of the discharge pipe 1207.

[0059] Local working principle: The cleaning and disinfection water containing feces will fall into the top of the filter 9, and the feces will be retained on the top of the filter 9 after filtration. When a lot of feces accumulates on the top of the filter 9, resulting in a decrease in the filtration rate, the pulling component is used to control the slide 1206 to move toward the discharge pipe 1207, pushing the feces toward the inside of the discharge pipe 1207, and then cleaning the surface of the filter 9. After cleaning, the slide 1206 will be reset.

[0060] In this embodiment, the pulling assembly includes a second sleeve 1201, a through pipe 1202, a second piston 1203, a first spring 1204, a connecting rod 1205 and a resistance member. The second sleeve 1201 is fixed at the middle position of the top of the discharge pipe 1207 and is connected to the inner top of the disinfection filter box 6. A through pipe 1202 is provided between the rear end of the second sleeve 1201 and the bottom of the disinfection filter box 6. A second piston 1203 is slidingly provided inside the second sleeve 1201. A first spring 1204 is provided between the second piston 1203 and the end of the second sleeve 1201. A connecting rod 1205 is provided between the outer side of the second piston 1203 and the slide plate 1206. A resistance member is provided between the second piston 1203 and the outer side of the second sleeve 1201. The resistance member provides constant resistance to the movement of the second piston 1203.

[0061] Local working principle: During the filtering process, the interior of the second sleeve 1201 and the interior of the disinfection filter box 6 are also in a negative pressure state. Since the second piston 1203 is blocked by the resistance applied by the resistance member, the position of the second piston 1203 is limited. When the filter screen 9 is blocked, the negative pressure inside the disinfection filter box 6 increases, which is greater than the resistance applied to the second piston 1203 by the resistance member. At this time, the second piston 1203 slides toward the inner end of the second sleeve 1201 and squeezes the first spring 1204. The movement of the second piston 1203 will drive the movement of the slide plate 1206 through the connecting rod 1205. After the feces on the surface of the filter screen 9 is cleaned, the negative pressure inside the disinfection filter box 6 is reduced, and the second piston 1203 is reset under the elastic force of the first spring 1204, and the slide plate 1206 is also reset accordingly.

[0062] In this embodiment, the resistance member includes a slide groove 1208, an insert block 1209, a second spring 1210 and an annular groove 1211. The slide groove 1208 is opened on the circumferential surface of the second piston 1203. The insert block 1209 is slidably arranged inside the slide groove 1208. A second spring 1210 is arranged between the insert block 1209 and the end of the slide groove 1208. An annular groove 1211 is opened on the inner side of the second sleeve 1201. The end of the insert block 1209 is inserted into the inner side of the annular groove 1211. The inner side of the annular groove 1211 is arc-shaped.

[0063] Local working principle: The plug 1209 is designed to be radially telescopic. Under the action of the second spring 1210 (elastic coefficient 5-10N / mm), its end is always embedded in the arc-shaped inner wall of the annular groove 1211. The depth of the annular groove 1211 along the axis of the second sleeve 1201 is 3-5mm, forming a sliding friction force as a constant resistance. When the filter 9 is blocked and the negative pressure in the disinfection filter box 6 is ≥20kPa, the negative pressure force (F=negative pressure×piston area) exceeds the resistance (10-15N), pushing the second piston 1203 to overcome the spring force and move, driving the slide 1206 to scrape off the feces on the surface of the filter 9. When the blockage is relieved and the negative pressure is <10kPa, the first spring 1204 (elastic coefficient 20-30N / mm) resets the piston.

[0064] In this embodiment, one end of the insert block 1209 located inside the annular groove 1211 is semicircular in shape, and the end of the insert block 1209 and the inner side of the annular groove 1211 are provided with a wear-resistant coating.

[0065] Partial working principle: The use of wear-resistant coating can reduce the wear inside the insert 1209 and the annular groove 1211, thereby increasing the service life.

[0066] The above is only a further embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solutions and concepts of the present invention within the scope disclosed by the present invention, which fall within the scope of protection of the present invention.
